(57) The spots to be bonded are determined by a light intensity controller as data and
bonding is carried out in accordance with the data. The data obtained are stored in
a memory or disk memory. In the case of storing the data in the memory, the data is
transmitted to a wire bonder as occasion demands, and the wire bonder carries out
bonding in accordance with the received data. In the case of storing the data in the
disk memory, the disk memory is mounted on the wire bonder. The wire bonder reads
out the data from the disk memory as occasion demands and carries out wire bonding.
